Same anecdote for me (except I'm +/- 40 years experience). I consider my self a pretty good dev for non-web dev (GPU's, assembly, optimisation,...) and my conclusion is the same as you: impressive and scary. If the somehow the idea of what you want to do is on the web in text or in code, then Claude most likely has it. And its ability to understand my own codebases is just crazy (at my age, memory is declining and having Claude to help is just waow). Of course it fails some times, of course it need direction, but the thing it produces is really good.
